Rotary hammer is a heavy-duty power tool for drilling and chipping tough materials like concrete, stone, and masonry, combining a powerful rotary motion with a strong, electropneumatic hammering action that creates forceful, rapid impacts. Unlike standard or impact drills, rotary hammers feature an advanced impact mechanism that provides significant power for effortless material penetration and can also be used with attachments for chiseling, demolition, and other heavy-duty tasks.
